MPs have voted against a proposal to delay Brexit in order to prevent the UK leaving without a deal.

The amendment had been put forward by Labour MP Yvette Cooper, but was rejected by 23 votes.

MPs are voting on changes to Theresa May's Brexit plan before she seeks a re-negotiation of it with the EU.

The prime minister has urged MPs to back another amendment that would propose "alternative arrangements" to the controversial Irish backstop plan.

The backstop is the insurance policy in Mrs May's plan to prevent checks on goods and people returning to the Northern Ireland border, which some MPs fear could leave the UK tied to the EU's rules indefinitely.

It was a key part in seeing her original Brexit deal voted down in Parliament by an historic margin earlier in January.

Mrs May said she knew there was a "limited appetite" in the EU for changes to the deal, but she believed she could "secure" it.

She had phone calls with key EU leaders throughout the day ahead of the Commons votes and has already spoken to the President of the European Commission Jean-Claude Juncker and the Irish Taoiseach (Prime Minister) Leo Varadkar.

But the EU has said it will not re-open negotiations and change the legal text agreed with the UK PM.

MPs are currently voting on an amendment put forward by Tory MP Caroline Spelman and Labour MP Jack Dromey with the aim of preventing a no deal Brexit.

Mr Corbyn's amendment was voted down by 327 votes to 296, Mr Blackford's only saw 39 votes of support, compared to 327 votes against, and Mr Grieve, who wanted MPs to be given six days to debate Brexit alternatives, lost by 321 votes to 301.

This was followed by Ms Cooper's, which lost by 321 votes to 298, and one by Labour MP Rachel Reeves - also trying to postpone Brexit - which lost by 322 votes to 290.

There are two more amendments to be tabled that could be voted on - including one from Tory MP Sir Graham Brady, calling for an "alternative" to the Irish backstop, which Tory MPs have been ordered to back.

Mrs May earlier appealed for the backing of the "Brady" amendment, saying it would "give the mandate I need to negotiate with Brussels an arrangement that commands a majority in this House - not a further exchange of letters, but a significant and legally binding change to the withdrawal agreement".

Nigel Dodds, the Westminster leader of the Democratic Unionist Party (DUP) - whose MPs Mrs May's government relies on to win key votes - welcomed the announcement, saying: "From day one... we rejected the backstop and argued for legally binding change within the withdrawal agreement."

And the pro-Leave European Research Group, led by Jacob Rees-Mogg, has said it will vote in favour of Sir Graham's amendment.

If MPs back Sir Graham's amendment, it could pave the way for a plan known as the "Malthouse Compromise".

Engineered by both Leavers and Remainers, the proposal includes extending the transition period for a year and protecting EU citizens' rights, instead of using the backstop.

Quick guide: What is a no-deal Brexit?

A "no-deal" Brexit is where the UK would cut ties with the European Union overnight without a transition period.

Theresa May's government, and many others, believe this would be hugely damaging and want a more gradual withdrawal. But if Parliament can't agree on that, and nothing else takes its place, the UK could still leave without a deal.

This would mean the UK would not have to obey EU rules. Instead, it would need to follow World Trade Organization terms on trade. Many businesses would see new taxes on imports, exports and services, which are likely to increase their operating costs. That means the prices of some goods in UK shops could go up.

The UK would also lose the trade agreements it had with other countries as a member of the EU, all of which would need to be renegotiated alongside the new agreement with the EU itself.

Manufacturers in the UK expect to face delays in components coming across the border.

The UK would be free to set its own immigration controls. However some UK professionals working in the EU and UK expats could face uncertainty.

Some countries, such as Spain, Germany and the Netherlands, have given temporary guarantees about residency status and rights, but there is not yet an agreed policy for UK citizens across the EU in the event of a no-deal Brexit.

The situation for holidays and business trips is a little clearer, as the European Commission has said that even in a no-deal scenario, UK travellers won't need a visa for short visits of up to 90 days.

The border between Northern Ireland and the Irish republic would become an external frontier for the EU with customs and immigration controls, though how and where any checks would be made is not clear.

Some Leave supporters think that leaving without a deal would be positive if the right preparations were made. They say criticism is scaremongering and any short term pain would be for long term gain.

But critics - including both Brexit supporters and opponents - say that leaving without a deal would be a disaster for the UK: driving up food prices, leading to shortages of goods and gridlock on some roads in the South East resulting from extra border checks.

Mrs May also promised MPs the votes on Tuesday would not be the last chance for them to express their views over Brexit.

She said that if no new deal is reached by 13 February, she will make a statement to Parliament that day and table an amendable motion for debate the following day, re-opening discussions on how to move forward with Brexit.

EU 'unlikely to entertain changes'

The excitable interventions we're witnessing in Parliament will convince EU leaders even more deeply that MPs are still very divided over Brexit and that now is not the decisive moment for Brussels to budge.

The EU wants to avoid an endless process of Theresa May shuttling to and from Brussels, getting a tweak or two, returning to Parliament, having the deal still rejected, coming back to Brussels and so on.

It's right to think the EU sometimes insists one thing, then does something rather different.

But the Irish backstop is a hugely sensitive issue, painfully co-negotiated over months with UK negotiators and almost impossible to fudge (as the EU prefers to do in difficult situations).

EU leaders are unlikely to touch the conditions of the backstop until a no-deal Brexit is well and truly staring them in the face. And even then they are unlikely to entertain changes unless Dublin is on board.
